Carbon dioxide/epoxide copolymerization is an efficient way to add value waste CO2 and reduce pollution in polymer manufacturing. Using this process make low molar mass polycarbonate polyols a commercially relevant route new thermosets polyurethanes. In contrast, high polycarbonates, produced from CO2, generally under-deliver terms of properties, one the most widely investigated, poly(cyclohexene carbonate), limited by its elongation at break brittleness. Here, catalytic polymerization...
A new series of block polyester thermoplastic elastomers are prepared by a one-pot procedure; they show properties competitive or better than conventional materials and can be fully degraded after use.
Miniaturised test specimens are often used for the tensile testing of cellulose nanopapers as there currently no standardised geometries to evaluate their properties. In this work, we report influence specimen on measured properties plant-derived nanofibres (CNF) and microbially synthesised bacterial (BC) nanopapers. Four were studied: (i) miniaturised dog bone with 2 mm width, (ii) rectangular 5 (iii) standard width (iv) 15 width. It was found that moduli both CNF BC not significantly...
Volumetric N 2 adsorption at −196°C is generally accepted as “gold standard” for estimating the Brunauer-Emmet-Teller (BET) surface area of nanocellulose. It unclear however, whether BET nanocellulose obtained such low temperatures and pressures meaningful an absolute sense, used ambient temperature pressure. In this work, a systematic evaluation using highly crystalline bacterial cellulose (BC) model was undertaken to achieve comprehensive understanding limitations method volumetric...
Cellulose nanofibers are often explored as biobased reinforcement for the production of high-performance composite materials. In this work, we fabricated transparent poly(methyl methacrylate) (PMMA) composites consisting two-dimensional and three-dimensional bacterial cellulose (BC) nanofiber networks. Three different designs 1 vol % BC loading were studied: (i) with a network embedded uniformly throughout PMMA matrix; (ii) sandwich-structured construction BC-PMMA sandwiched between two neat...
Abstract Nanocellulose network in the form of cellulose nanopaper is an important material structure and its time-dependent mechanical response crucial many potential applications. In this work, we report influences grammage strain rate on tensile bacterial (BC) nanopaper. BC with grammages 20, 40, 60 80 g m −2 were tested tension at rates ranging from 0.1% s −1 to 50% .
